为充分利用太阳能，延长蓄电池使用寿命，提出了基于最大功率点跟踪(maximum power point tracking，MPPT)的蓄电池充电控制策略。MPPT控制采用改进的变步长扰动占空比控制算法。该策略将 MPPT 充电和阶段式充电相结合，保证了直流母线电压的稳定；给出了双向直流变换器的控制策略。仿真算例结果验证了该策略的有效性。

To fully utilize solar energy and increase service life of battery, a battery charging control strategy based on maximum power point tracking (MPPT) is proposed, and the improved variable-step perturbation duty ratio control algorithm is applied to MPPT control. The proposed control strategy combines MPPT charging with stage-style charging to ensure the voltage stability of DC bus, and for this purpose a control strategy for bi-directional DC-DC converter is given. Finally, a simulation example is given to demonstrate the effectiveness of proposed control strategy.
